CatchAll Activator

CatchAllActivator can be used in JAICF project to handle any user's query request that wasn't handled by any other activator.

Usually this activator is used to handle all raw user's input for some purposes (for example, if user dictates a text of reminder note).

It also can be used as a fallback state to handle a request that can't be handled by any other state. We recommend to use a fallback builder for this purposes.

How to use

All you need to use this activator in your JAICF project is to add catchAll activators to the scenarios and then append CatchAllActivator to the BotEngine's array of activators.

catchAll activator

state("fallback", noContext = true) {
    activators {
        catchAll()
    }

    action {
        reactions.say("Sorry, I didn't get it... Could you repeat please?")
    }
}

CatchAll context

Once a CatchAllActivator activates some state, a CatchAllActivatorContext instance becomes available through an activator.catchAll variable in the action block of this state. It doesn't contain any data but can be used to determine if the state was activated by CatchAllActivator.

Note that is you need to obtain a raw user's request text, you can use request.input in your action block.

state("state1") {
    activators {
        intent("SomeIntent")
        catchAll()
    }

    action {
        activator.catchAll?.run {
            reactions.say("This state was activated by catchAll activator because you've said ${request.input}.")
        }
    }
}
